cell needs a specific machine, it will select a blueprint, copy it, and then
build the machine it needs. The biological term for such a blueprint is "gene".
+Using the instructions stored in a gene, the ribosomes build up other molecules
+called proteins. Proteins that perform some sort of chemical reaction are the
+enzymes I was talking about a bit earlier. Ususally, if your focus is on what
+the thing is made from, you'd call it a protein, and if your focus is on the
+function, you'd say "enzyme". So let's have a look at how proteins are made.
+
+As mentioned before, the instructions on how to build a protein are stored in a
+blueprint, the gene. Genes are encoded on nature's universal storage system, a
+molecule called "desoxyribonucleic acid", or in short DNA.
